Re: Probe Cables for 16801A Logic Analyser
Thanks for the correction Mark. You're right, it's the 50 pin connector - it fits my 16555 - 557. I was careful to avoid the ones with 40 pins each end (suits the 1650) but hadn't appreciated the

Re: 8566B 85660-60206 Main Coil Driver C7 Tantalum replacement
The reason there was a tantalum in that place has to do with its small size when compared to an electrolytic. Don't bother looking for a tantalum replacement and keep the same capacitance value. It

8566B 85660-60206 Main Coil Driver C7 Tantalum replacement
I'm in the process of overhauling a 8566B Spectrum analyzer. Some of the boards have the non mil spec wet slug tantalums that are leaking and corroding from the rubber end seals and I am looking for

Re: HP 5086-7906 YTO
Hi Adri, Glad to hear you finally managed to get that 8595E back up and running. As for the software, I wrote it in vb.net. It only does basic tests: Flatness test and save calibration constants table

Re: Probe Cables for 16801A Logic Analyser
Careful on that first link for ebay item #395285104946.? Although it's a "40-pin cable" on the probe side, the chassis-side connector is not compatible with the 16801A.? There are a lot of different

Re: Introduction
This sparked a thought and looking I see that there are two libraries for interfacing with GPIB available for TCL., GPIB-Tcl and GPIB-tclsrq. The latter supports callbacks on SRQ events and is more

For the x1 and x100 ohm ranges the 260 outputs 1.5 vdc, on the x10000 it outputs 9vdc! On the x1 range the short circuit current is 125 ma, on the x100 it¡¯s 1.25 ma, on the x10000 it¡¯s 75 ua.

Re: HP 8554B, no RF after first successful run...
Take a silicon diode or a shottkey diode.? Put a current meter in series with it and measure the resistance.? Now you know how much (at a minimum) your meter will dump into the diode. Try the same

Re: HP 5086-7906 YTO
Yves, your mention about the SW related to the flatness test is interesting. Is it software written by you or does it exist on the market? As for my 8595E I suspected that the intermittent spikes

Hi Jim, Uh Jim¡­ I think you meant to say ¡°Cadillac¡± for the HP 8566A. It is a great Analyzer. Much earlier in my career, I would **beg** to use one for what I was working on. Very intuitive
